I'm a little confused by PGA head room.

would you teach me a little more for my application.

when I use AIN1 as psuedo differential bipolar mode(AVDD=5V, VREF=5V, AINCOM=2.5V, Gain=128), 

what are PGA output signal differential range? -3.75V<Vout-diff<3.75V?

and what is the common mode voltage? VREF/2=2.5V?

but, as are PGA output signals(voutp,voutn)  2.5-3.75/2<voutp,voutm<2.5+3.75/2 ?

so, I can't utilize full ADC input range from -VREF to VREF, am I right?
